p speciacaiion ofv Leners Patent. Application filed January 19,1911, Serial No. 603,526. 'Renewed June .7, A1912. Serial No. 702,363.

i To all w/Lom t may concern.' l l Be itknown that I, GEORGE E. l?1n;.r'.1s sinn, citizen of the UnitedStates, and resident of Jersey City, in the county of Hud- 5 son and StateofNewJersey, have invented certain" new and useful Improvements in,

Rail-Grinders, of which the following is a specification.

This invention relates to certain improvements `in rail grinders and lmore particularly lto vthat type which embodiesv a truck cari v1ngV a grinding member so mounted that when the truck is moved along.l the track the grinding vmember will be moved alongv the-rail :forming .a portion of the track vE to `remove surface irregularities therein.l i j The object of the invention specifically claimed in this application is to provide an automatic lowering and raising ofthe grinding member bodily'v with the truck' frame during the propelling of the truck along the track to accomplish the removal .of sharp depressions in the rail,las at so-.calledV 1.75"? poundedjoints, by forming a long shallow depresslon merging "into the .straight portions of the rail surface.

Other objects' and Vadvantages as specifi# cally claimed in this application will be set tion, which should be read' -in connection 'with the iillustrative;n -embodiment of the invention shown. in the accompanying drawings in whicl1,-' Y

.Figure 1 .is a top'plan view of a rail grinder constructed in accordance with my invention, a portion thereof being broken away and a portion being shown on the line 1-1 ofFig. 3.; Fig. 2 is a vertical longi- 40 tudinal section on the line 2 2 of Fig. 1;

Fig. 3 is a transverse vertical section, the power means for one of the grinding'members being removed; Fig-4 is an enlarged face view of the wheel vshown at the left end 45 view of Fig. 2, the axle being adjusted to eccentric position; Fig. 5 is a sectional View of the wheelshwn lnF 1g. 4, and Figs. 6,

7, and 8 are diagrammatic views illustrating.

different positions assumed by the grinder 50 during the operation of removing a sharp dip' or depression in\the rail. j

In the specific `formof my invention here illustrated, I- mount the grinding members,

which are preferabll'femery' wheelsupon al ttmck having aimamramel formed 4of forthhereinafter in the-following specifica# 'ystat-ed, is preferably inthe form of :emery wheel. This emery `wheel is of any i .channeliron4 Adjacent opposite ends Vof .the frame are bearings for the axles 11 and 12, andvupon these `axles are pairs of wheels 13 and 14 mountedto travel .along the rails forming the track. Extending across the frame intermediate the ends thereof is a cross-rail 15 serving'as-.al support for the grinding members.4v This cross-rail is illustratedas being rigidly secured in place at a lpoint somewhat nearer the axle 11 than the axle 12, but'it is evident that the cross- Vrail might be secured in placeat any point along the length of the frame of the truck might be so 4mounted as to facilitate its adjustment fromone position to another. Mountedupou this cross-rail or .guide are -twosad'dles or slides 16 so constructed as to be retained'in engagement with the cross- `rail, but being adjustable along the length thereof vin Va direction transversely of the, track.

Preferably. these saddles have removable flanges' 17 for `retaining them. in position and by the removal of which the saddles may be taken O the cross-rail. Extending lengthwise of the l`rail'are two screw rods 18 provided with handles 19 at their outer ends and .having threaded engagement with projections 20 on the saddles so that by turning 'the handles the saddles may be ldrawn along the cross-rail to any position desired.

Mounted upon each saddle or horizontally movable slidelwis a bracket or-vertically movable slide 21.` These brackets may be retained in engagement with the saddles in any suitable manner, but preferably by means of a dove-tailed guide and-guid'eway as shown in the'upper portion of Fig. 1. vertically disposed within each bracket is a screw rod 22 having a yhandle 28 at its upper end and having threaded engagement with the projection 24 on the saddle'so that by turning the handle 23 the bracket may be raised or'lowered. This raising or lowering of thebracket isindependent and unaffected by the lateral movement of the saddle. Each bracket has dependin arms carrying a shaft 25 toone end o which is secured a grinding member 26 which, as hereinbefore an shape or contour desired,y dependent upon the shape and character of the rail to 'be ground and the nature ofthe irregularitles Patented July 3o, 1912.
